Answer:
Differences are listed below:
Explanation:
Weight: Plastic can weigh appreciably much less than than metal.A plastic part weighs approximately one-sixth of the same part in steel.
Chemical resistance:Plastic are much less likely to suffer chemical attack and don not corrode.
Machinability: Plastic are much more easier to cut through than metal.
Product life: The life span for plastic is longer than of the metals in many applications.
Cost: The cost of plastic raw materials is appreciably less than of the metals.
Heat: Plastic are less heat resistive than metals.
Ultraviolet light can degrade the plastics soon.
Strength: Metal provides more strength than the plastic.
Answer:
It has dark lines in it that allow astronomers to determine what elements are in the star. red-shifted (shifted toward the red end of the light spectrum).
Explanation:
Answer:
capacitance of the capacitor = 0.18 μ F
Explanation:
Area of the plate A = 0.063 m x 5.4 m = 0.3402 m²
distance between the plate d = 3.5 × 10–5 m
dielectric value for Teflon K = 2.1
capacitance of capacitor = ?
Formula for capacitance of parallel plate is as follows ,
(Where 
)
putting the values in the equation,
C = 
=0.18 μ F
Bacteria,Worms, Slugs, Snails, and Fungi are all types of decomposers
The answer is b because kinetic energy is the energy of motion, while potential energy is the energy stored in an object because of its position.
